Auto-Disabling Dram Error Checking on Threshold

1. A method of disabling error checking in a dynamic random access memory (DRAM), the method comprising: receiving data at a DRAM, the receiving from a memory controller; executing, at the DRAM, error checking logic based on the data; detecting, by the error checking logic, an error condition in the data; determining, at the DRAM, whether detecting the error condition in the data causes an error threshold to be reached; disabling the error checking logic at the DRAM in response to determining that detecting the error condition in the data causes the error threshold to be reached; and communicating the error condition to the memory controller in response to determining that detecting the error condition does not cause the error threshold to be reached.

2. The method of claim 1 , wherein the disabling is performed by the DRAM.

3. The method of claim 1 , wherein the error condition is a parity error and the data includes command or address data.

4. The method of claim 1 , wherein the error condition is a cyclical redundancy check (CRC) error and the data includes write data.

5. The method of claim 1 , wherein the DRAM is a double data rate fourth-generation synchronous DRAM (DDR4).

6. The method of claim 1 , wherein the error threshold is determined to be reached based on a number of the error conditions previously detected exceeding a threshold count.

7. The method of claim 1 , wherein the communicating is via an alert signal.

8. The method of claim 1 , wherein method further comprises, in response to the communicating, receiving the data at the DRAM from the memory controller.

9. A memory system comprising: a memory device, the memory device including a dynamic random access memory (DRAM) configured for: receiving data at the DRAM, the receiving from a memory controller; executing, at the DRAM, error checking logic based on the data; detecting, by the error checking logic, an error condition in the data; determining, at the DRAM, whether detecting the error condition in the data causes an error threshold to be reached; disabling the error checking logic at the DRAM in response to determining that detecting the error condition in the data causes the error threshold to be reached; and communicating the error condition to the memory controller in response to determining that detecting the error condition does not cause the error threshold to be reached.

10. The system of claim 9 , wherein the error condition is a parity error and the data includes command or address data.

11. The system of claim 9 , wherein the error condition is a cyclical redundancy check (CRC) error and the data includes write data.

12. The system of claim 9 , wherein the DRAM is a double data rate fourth-generation synchronous DRAM (DDR4).

13. The system of claim 9 , wherein the error threshold is determined to be reached based on a number of the error conditions previously detected exceeding a threshold count.

14. The system of claim 9 , wherein the communicating is via an alert signal.

15. The system of claim 9 , wherein method further comprises, in response to the communicating, receiving the data at the DRAM from the memory controller.

16. A computer program product for disabling error checking in a dynamic random access memory (DRAM), the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by processing circuitry to cause the processing circuitry to: receive data at the DRAM, the receiving from a memory controller; execute, at the DRAM, error checking logic based on the data; detect, by the error checking logic, an error condition in the data; determine, at the DRAM, whether detecting the error condition in the data causes an error threshold to be reached; disable the error checking logic at the DRAM in response to determining that detecting the error condition in the data causes the error threshold to be reached; and communicate the error condition to the memory controller in response to determining that detecting the error condition does not cause the error threshold to be reached.

17. The computer program product of claim 16 , wherein the error condition is a parity error and the data includes command or address data.

18. The computer program product of claim 16 , wherein the error condition is a cyclical redundancy check (CRC) error and the data includes write data.

19. The computer program product of claim 16 , wherein the DRAM is a double data rate fourth-generation synchronous DRAM (DDR4).

20. The computer program product of claim 16 , wherein the error threshold is determined to be reached based on a number of the error conditions previously detected exceeding a threshold count.
